Answer:
0.218
Step-by-step explanation:
If the sound of the quietest noise a person can hear is x, then the sound of the normal conversation is x(10^6). Also, the sound of the jet at takeoff is x(10^14). When we divide x(10^14) by x(10^6), we get the answer that is equal to 10^8. Thus, the sound of jet at takeoff is 10^8 times that of the normal conversation.
The movie would be 1 hour 45 minutes long
225 perch. You set up the equation 4/3=300/x. Then you cross multiply to get 4x=900, then you divide each side by 4 which makes x=225
Answer:
62.5% increase
Step-by-step explanation:
First step : find the difference between two numbers, in this case, it's 1300000 - 800000 = 500000.
Second Step: Take the difference, 500000, and divide by the original number: 500000/800000 = 0.625.
Last, multiply the number above by 100: 0.625*100 = 62.5%. You're done! You calculated difference of a number in percent, and the answer is a percentage increase of 62.5%.
